TAKING it there is the easy part.
Registering, changing all lenses and other stuff to "E" approved ones and getting it through TÜF... You're begging trouble. I have lived over 30 years in Europe, so only thing I can advise you is not to do it.
What you do is up to you.
By the way, do you know that TÜF does not approve ANY modifications, such as aftermarket exhaust pipe, non original carb, sprockets... If you have any aftermarket parts on the Moby, you better have papers to prove it's approved in Germany on that specific year and model of your moped. They do not negotiate on these, so crying or whining does not help.
See now what I mean?
